[image]Martian Gullies - NASA/JPL/Malin Space Science Systems
14 July 2004 This Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC) image shows gullies with banked and somewhat sinuous channels and inner channels cut into the wall of a south middle-latitude crater near 46.6S, 175.7W. Banked channels are among the key evidence suggesting that some martian gullies involved flowing fluids with all of the physical properties of liquid water. The image covers an area about 2.3 km (1.4 mi) wide, and is illuminated by sunlight from the left.
